SPECIFICATION forming part of Letters Patent No. 554,188, dated February4, 1896. Application lil'ecl July 13,1895. ASerial No. 555,856. (Nomodel.)

.To all whom t may concern.'

Beit known that we, JOSEPH K. JOHNSTON and WILLIAM B. JOHNSTON, citizensof the United States, and residents of Anderson, in the county ofMadison and State of Indiana, have invented certain new and usefulImprovements in Apparatus for Forcing Vater and other Liquids from Gasor other Wells; and we do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawing, and to letters of referencemarked thereon, which forms a part of this specication.

The ligure ofthe drawing is a vertical sectional view of the invention.

This invention has relation to apparatus for forcing water or otherliquids from natural-gas wells, and is designed to provide means ofimproved character wherein the pressure of the gas is used to force thewater to the top of the well.

The invention also provides means whereby the gas and water pipes may becleared when necessary.

XVith these objects in view the invention consists in the novelconstruction and combination of parts, all as hereinafter described andpointed out in the appended claim.

Referring to the accompanying drawing, the letter A designates thedrive-pipe of a natural-gas well, which is driven through the soil,sands, and drift tothe limestone rock upon which it rests, as indicated.

B designates the casing, which extends from the top of the well throughthe drive-pipe down to the shale rock upon which it rests, as shown.Below this pipe the rock constitutes the wall of the well. Said pipe isusually from five to five and five-eighths inches in diameter.

. O designates the water discharging or separator pipe, which extendsfrom above the ground to the bottom of the well, its lower portion Obeing perforated to admit water.

c is a stop-cock at the upper portion of the pipe C.

D is the gas-pipe which surrounds the waterpipe O and extends from abovethe ground to the bottom of the well, its lower portion D beingperforated. The upper end of the pipe D is connected by a coupling D2 toa pipe D3 D4, which is connected to a gas-main E which has other wells(not shown) also connected thereto.

F is a stufling or packing box for the pipe C, where it passes out ofthe coupling D2, said box having a nut F and packing f of hemp or likematerial, upon which the nut seats.

G is a small pipe which connects the pipe D3 with the pipe O and is forthe purpose of admitting gas to the latter to blow it out whenever theperforations at the bottom thereof become clogged or choked.

g is a cock in said pipe.

g is a gate-valve in the pipe D3. I-I is a blow-oli for the pipe D, andh is th valve thereof.

I is a packer which is placed around the pipe B just above the line ofthe Trenton or gas-bearing rock, and which confines the water and gasbelow it.

The operation is as follows: By closing the gate-valve g/ and openingthe valve c there will commonly be pressure enough in the well toforce'the water into the pipe O and raise it to the surface anddischarge it. It frequently happens, however, that after a well has beenflowing for some time, the pressure of the gas becomes too weak toaccomplish this result. When this occurs the valves c and g are opened,and the gas from the main E iiows down the pipe D into the bottom of thewell, and being coniined below the packer D creates a pressuresufficient to force the water into pipe C and discharge it. The wellbeing cleared of water the valve g is left open, and the gas in the wellrises intothe main E.

By opening the valve g at any time the pipe O may be blown out.

By opening the valve 71. the pipe D may be blown out.

I-Iaving thusdescribed our invention, what we claim as new, and desireto secure by Letters Patent, is

The combination of the gas-discharging pipe D, which extends to thebottom of the well, its lower portion being perforated and its upperportion connected to a gas-main IOO which is also connected to otherWells, the stantially in the manner and for the purpose Waterdischarging pipe O which extends described.
